Marinonicoris myrmecoides Carvalho – Wikispecies link – Pensoft Profile
- Marinonicoris myrmecoides Carvalho, 1988: 877 (orig. descrip.); Carvalho and Froeschner 1990[1]: 328 (type data, depository); Schuh 1995[2]: 141 (cat.); Carpintero et al. 2006[3]: 8 (list, distr.).
Diagnosis
This species (Figs 93, 94) is recognized by the generic characters, including the swollen pronotum, constricted hemelytra, the golden and silvery scale-like setae on the clavus and corium, the lack of erect, bristle-like dorsal setae, and the male genitalia, especially the parameres (Figs 280, 282).
Description
Male (n = 2): Length 2.98–3.36 mm, width 1.14–1.18 mm. Head: Width 0.72–0.77 mm, interocular width 0.30–0.34 mm. Labium: Imbedded in glue. Antenna: Segment I, length 0.16–0.21 mm; II, 0.51–0.58 mm; III, 0.30–0.37 mm; IV, 0.34–0.40 mm. Pronotum: Length 0.51–0.58 mm, basal width 0.91–1.04 mm.
Coloration: Head: yellow brown to dark brown. Antenna: Segment I yellowish brown, with a red streak on inner margin; segments II–IV dark brown. Pronotum: Dark brown, area around calli sometimes slightly paler brown. Scutellum: Brown. Hemelytron: Dark brown, area on basal half of corium and clavus appearing paler brown because of setal coloration. Ventral surface: Thoracic area yellowish brown, mesopleural area with a glaucous sheen; abdomen dark brown to fuscous, glaucous stridulatory patch distinct. Ostiolar evaporative area: Dark brown, with a red knob at middle of auricle. Legs: Dark brown, apices of hind femora and tibiae and all of tarsi and claws pale yellowish brown.
Structure, texture, and vestiture: As in generic description. Head, pronotum, and hemelytra shiny. Labium: Extending about to hind coxae or base of abdomen. Each hemelytron with two rows of silvery scale-like setae, one across the base of the corium and clavus, and one across the middle of the corium and apex of the clavus; area between densely covered with golden scale-like setae (but lacking erect, bristle-like setae).
Male genitalia: Left paramere (Fig. 280): Elongate, distal stem-like, with beak-like apex elongate, basal half stouter with a short, slender, apically rounded arm. Right paramere (Fig. 282): Stout, with a slender, apically bifid arm near base. Phallotheca (Fig. 281): Stout, apex with three comb-like processes.
Female (n = 4): Length 2.62–2.98 mm, width 1.02–1.18 mm. Head: Width 0.70–0.72 mm, interocular width 0.30–0.35 mm. Labium: Imbedded in glue. Antenna: Segment I, length 0.16–0.18 mm; II, 0.50–0.53 mm; III, 0.55 (others missing) mm; IV missing. Pronotum: Length 1.00–1.03 mm, basal width 0.80–0.91 mm. Similar to male in color, texture, and vestiture.
Distribution
Previously known only from the holotype taken in Paraná, Brazil. Carpintero et al. (2006)[3] reported specimens from Argentina, Paraguay, and Uruguay. Rio Grande Norte is a new Brazilian state record.
Host
Unknown.
Discussion
The holotype, though not borrowed, was examined during a visit to the Museu Nacional collection (MNHN) in Rio de Janeiro. This species is easily distinguished by the structure of the male genitalia.
